 No. 3 and 4. 1905. p. 176—189.) 



These plants were collected mainly on the Pacific slope of the 

 Rocky mountains, where the moisture of the atmosphere and the genial 

 climate conditioned by the Japan current produce a most luxuriant Vege- 

 tation. Introduced plants (e. g. Cytisus scopariiis, Digitalis ptirpurea 

 -etc.) attain vast proportions and the trees, especiaily the Conifers, are 

 phenomenaliy large (thus alders (Alniis) are seen 2 or 3 feet in diameter with 

 a corresponding height). — The greater part of the paper consists of a list 

 of the rarer plants observed. F. E. Fritsch.
